説明
Patients with acoustic neurinoma present sudden hearing loss as a initial symptom are increasing.<BR>However, specific type of audiogram for acoustic neurinoma has not yet been described.<BR>In our institutes between 1981 and 1993, there were 81 cases of acoustic neurinoma, in whitch 33 cases complained chiefly of a sudden hearing loss. But the other 48 cases complained of a slowly progressive hearing loss (nonSD-AT). Pure tone audiograms of 17 in 33 cases before treatment as sudden deafness (SD-AT) were analyzed.<BR>The medio-cochlear type audiogram was observed in 11 patients out of 17 with SD-AT, on the other hand this type was not obserbed in non SD-AT group. The hearing loss in high (8kHz) and low (125Hz, 250Hz) frequencies of SD-AT was significantly smaller than that of nonSD-AT. From these results, it was emphasized that any patients with sudden hearing loss of “medio-cochlear type” must be carefully studied for possible acoustic neurinoma.
